The NIH option to use ASSIST, the Application Submission System & Interface for Submission Tracking, is now available for single-project applications such as R01s and R21s

This is a web-based system that was previously only available for multi-project (multi-component or complex) grant applications that use the SF424 form set.  Use of this system allows for multiple individuals to work on the application package concurrently.  Please contact your GPS if you’re interested in using this system for your next submission.
